Our spyder housing is different. It is stronger and made for racing. This was a very important part for a lot of our wins, including the success of the winning (Maxxis Club Malaysia) 119 car at the Rainforest Challenge 2016, 2017.
Lately, we have seen a few copies of the spyder gears we offer. Note that the Spyder gears made by us have a CROSS inside connecting 6 gears all together. The outer design is like in the photo below.
